T1027 Obfuscated Files or Information
The sample exhibits significant slack space anomalies and contains XOR-encoded strings, indicating a deliberate attempt to obfuscate its contents. While no specific malicious behavior like script execution or network communication was directly observed in the provided excerpts, these indicators strongly suggest the file is malicious. The obfuscation techniques point towards an attempt to hide malicious payloads or delivery mechanisms.
Heuristics 2
-
XOR-encoded strings (key 0x92) critical SC_XOR_ENCODEDFound 2 Windows library/API name(s) XOR-encoded with single-byte key 0x92: 'advapi32.dll', 'shell32.dll'
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 91,648 bytes but its declared streams total only 22,175 bytes — 69,473 bytes (76%) live in unallocated sector slack. This is the canonical hiding place for pre-macro-era Office exploit payloads (XOR-encoded shellcode reached via a parser pointer-corruption bug in the document structure).
